SKIN-STRETCHING BOARD.

and State of Pennsylvania, have invented,

certain new and useful Improvements in Skin-Stretching Boards, of which the fol lowing is a specification.

y invention relates to improvements in skin stretching boards, the object of the invention being to provide a board to which the skin may be secured, and which comprises a plurality of parts all of which are movable relative to each other, so that the skin can be uniformly stretched in all directions. i

A further object is to provide a board of the character stated having means for compolling each one of the sections of the board to be moved away from a normal position, and permit the sections to be moved independently so as to allow the neck portion of the skin to be stretched after the body portion has been stretched or vice versa.

A further object is to provide aboard of the character stated which will be of extremely inexpensive construction, strong and durable in use. i

WVith these and other objects in view, the invention consists in certain novel features ofconstruction and combinations and a1'-.

rangements .of parts aswill be more fully hereinafter described and pointed out in the claims. 1

eral L-shape with their lower shorter members abutting together when the board is in closed position as shown in Fig. 1. 3 represents the end section which has beveled ends 4 adapted to engage the beveled upper ends 5 of the sections 1 and 2, so that when the several sections are together, they form a rectangular board with a r ectangular openingfi in the center thereof, and pre-- sent a smooth surface against which I the skin 8 indicated in dotted lines is secured by nails 9 or other suitable fastening means. "he sections 1, 2, and 3, arerpreferably wood, and theyare made upWof suitable boards and timbers, so that they present smooth surfaces at opposite sides, the sections being shown hollow, although they may be otherwise formed as the outer edgesof sections 1, and 2, metal blocks 10 are secured by bolts 11 and nuts 12. These blocks 10 have screw-threaded openings for the reception of rods 7, the latter having threaded ends to engage the threaded openings in the. blocks, and it is to: be understood that these ends of the rods? have right and left hand screwthreads at their respective ends and are provided at. one end with handholds 13 to facilitatetheir turning movement. One of i the rods 7 extends through openings 14 in metal blocks 15, connection attheir inner ends with the blocks 15. as shown at 17 in Fig.3. These rods 16 are positioned. at rightangles to the rods 7 ,and extend through the. end section 3 and have screw-threaded portions engaging screw-threaded openings inblocks 10 secured by bolts 11 and nuts 12 to the edge of end section 3. In other words, the blocks 10 of the end sections. are precisely like the blocks for the side sections, and hence. they are given similar reference characters and will be given the same reference characters in all of the different modifications hereinafter referredto. In operation, the skin 8 is secured by nails 9 to the sec. tions .1, 2, and 3, the neck portion of the skin being preferably secured to the end section 3. By manipulating the several rods 7 and 16, all of the sections can be moved relative to each other to stretch the skin. The preferable operation is to first separate sections 1 and 2, causingthewbody portion of the skin to stretch laterally or transversely, and then move the end section 3 to desired. On

, erred forms S11) 3011) Of 51 number stretch the neck portion of the skin and stretch the skin longitudinally. The invention, of course, is not limited to the par-' ticular manner of operation, as this will depend upon the judgment of the user, and the character of the skins stretched.

1n the modification illustrated in Figs. 4-, 5, and 6, I provide four sections 18, 19, 20, and 21, all having inclined ends '22 so that they can snugly fit together and comprise a the sections are in board when of the sections 21 is the others, so that its inwardly beyond the tion of a smaller skin than would be possible,

without this extension. The sections 18, 19, 20, and 21, are all moved by means of rods 24, a pair 01 such rods being extended through opposed sections and having right and left hand screw-threads at their respective ends engaging in blocks 10 as in the pre- The rods 2%, where they cross, are coupled by metal blocks 25 having openings 26 therethrough at right angles to each other through which the rods project. This detail of construction is clearly shown in Figs. 5 and 6. As the parts are normally operated in a horizontal position, the coupling blocks 25 are all that is necessary to hold the sections and permit all of the sec tions to be moved toward and awayrfrom their inner position as is desired in stretching the skin.

In the modification illustrated in Fig. 7, 1 have shown but two sections 27, and 28, which are movable toward and away from each 'otherby rods 29 having right and left hand screwethreads at their respective ends projected through blocks 10 as'in the other,

forms. By manipulating the rods,after the skin is secured to the sections, the sections may be moved away from each other to stretch the skin. I I

In all of the forms, it will be observed that 1 provide on the side sections at their upper ends, hangers 30 which permit the of such boards upon parallel bars (not shown), portion of the sections, 1 provide casters 31 which permit the board to be readily moved about the floor from one place to another.

With all forms of my improved board, it will be noted that all sections to which the skin is secured are movable, so that every portion of the skin. is stretched alike, and while I have illustrated my improvements in connection with boards having two, three, or four sections, would have it understood Games of this patent may be obtained for adjusted toward and and at the lower that my invention is not limited to the paras 1 may employ the general form and arrangement of parts 'ClGSCllbGd. without departing from my invention, and hence I do not limit myself to the precise details set forth, but consider myself at liberty to make such changes and alterations as fairly fall within the spirit and scope of the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. A skin stretching plurality of sections, blocks secured to the edges of the sectionsand having threaded openings therein, rodsprojected through the blocks and having threads engaging the threaded openings in the blocks, hand holds on the rods adapted to permit the turning,

of the rods, whereby the sections may be away from each other, and blocks coupling the rods at right angles to each other, substantially as described.

2. A skin-stretching board of the character stated comprising three sections, two of said sections of general L shape havingtheir longer ends inclined, anend section located between the inclined ends of the first-men tioned, section and having; inclined ends whereby when said sectionsare together, a rectangular opening is formed between them, and means for moving all of the sections, substantially as described. Y

A skin stretching board of ter stated comprising three sections, two of said sections of general L-shape having their longer ends inclined, an end section located between the inclined ends of the first-mentioned section and having inclined ends whereby when said sections are together, a

rectangular opening is formed between them,

parallel rods pro ected through the first-f mentioned sections and having screw-threaded engagement therewith, other rods projected through the last-mentioned section and having therewith, devices coupling the last-men screw threaded engagement tioned rods with one of the first-mentioned rods, and means on each of the rods for turning the same, substantially as described.
